On finite element approximation of fluid structure interaction by Taylor-Hood and Scott-Vogelius elements

Abstract

This paper focuses on mathematical modeling and finite element simulation of fluid-structure interaction problems. A simplified problem of two-dimensional incompressible fluid flow interacting with a rigid structure, whose motion is described with one degree of freedom, is considered. The problem is mathematically described and numerically approximated using the finite element method. Two possibilities, namely Taylor-Hood and Scott-Vogelius elements are presented and implemented. Finally, numerical results of the flow around the cylinder are shown and compared with the reference data.
